The rolling roller 23 is formed in an elongated cylindrical shape, and is held by a holding portion 24a (FIG. 11) of a retainer 24. In addition, the retainer 24 is provided with an uneven portion 2 formed at an end thereof.
4b (FIG. 9), the clutch lever 15 is locked and fixed. As shown in FIGS. 5 to 7, the clutch lever 15 has an uneven portion 15 a fitted to the uneven portion 24 b of the retainer 24, and the uneven portion 15 a of the clutch lever 15 and the uneven portion 24 b of the retainer 24 are fitted. By joining, the clutch lever 15 and the retainer 24 are mutually connected.

Although the clutch lever 15 and the retainer 24 are formed separately, the same number of uneven portions 15a and 24b having the same dimensions are provided respectively. Accordingly, the locking angle of the clutch lever 15 with respect to the retainer 24 can be freely selected (see the two-dot chain line in FIG. 6A).

By the way, as shown in FIG. 10, the inner peripheral surface of the outer frame body 25 is formed so that its diameter becomes gradually smaller at regular intervals, so that a wedge-shaped accommodating portion 25a is provided. The rolling roller 23 freely rotates at the large diameter portion D1 of the wedge-shaped accommodation portion 25a of the outer frame 25, and bites between the wedge-shaped accommodation portion 25a and the sleeve 22 at the small diameter portion D2 of the outer frame 25. .

Here, in the present invention, the rolling roller 2
3 is characterized in that it is configured such that its dispersion is suppressed by the magnetic force. That is, the rolling roller 2
3 is attracted to the sleeve 22 or the outer frame 25 by the magnetic force.

As the first method, 1) there is a method in which the rolling roller 23 is structured so as to be drawn to the outer frame 25. In this case, the rolling roller 23 is formed of magnetized material, and the outer frame 25 is formed of a magnetic material, whereby the rolling roller 23 is drawn to the outer frame 25. Conversely, by forming the outer frame 25 with a magnetized material and forming the rolling roller 23 with a magnetic material, the rolling roller 23 is similarly drawn to the outer frame 25. . In the above case, the sleeve 22
Is more effective when formed of a non-magnetic material.

As the second method, 2) there is a method in which the rolling roller 23 is structured to be drawn to the sleeve 22. In this case, the rolling roller 23
Is formed of a magnetized material, and the sleeve 22 is formed of a magnetic material, whereby the rolling roller 23 is attracted to the sleeve 22. Conversely, the sleeve 22
Is formed of a magnetized material, and the rolling roller 23 is formed of a magnetic material.
Will be drawn to. In such a case, it is more effective to form the outer frame 25 from a non-magnetic material.

To the small diameter side of the wedge-shaped accommodation portion 25a. By operating the clutch lever 15 in this manner, when the rotor 7 rotates in the reverse direction, the rolling roller 23 engages between the wedge-shaped housing portion 25a and the sleeve 22 to restrict the reverse rotation.

When the clutch means 14 is actuated (ON), the clutch lever 15 is urged by the spring 16 in a direction to increase the engagement of the rolling roller 23. Therefore, the effect of the clutch means 14 acts with high sensitivity, and quick reverse rotation can be prevented. Note that the clutch means 14 is turned on.
At this time, the motor operates smoothly without restricting rotation in the normal rotation direction.

On the other hand, when the clutch means 14 is not operated, that is, when the reverse rotation of the rotor 7 is not restricted, the operation lever 18
The clutch lever 15 is driven clockwise as shown in FIG. 4 or FIG. In this case, as shown in FIG. 7 (B), by rotating the clutch lever 15 clockwise from the neutral position N by + θ, the rolling roller 23 held by the holding portion 24a of the retainer 24 allows the outer frame to rotate. The body 25 moves to the large-diameter portion side of the wedge-shaped accommodation portion 25a. At this time, the rolling roller 2
3 is free in the wedge-shaped accommodating portion 25a, and does not restrict rotation in the forward and reverse rotation directions.

Incidentally, as described above, the rolling rollers 23
Is attracted to the sleeve 22 or the outer frame 25 by the magnetic force. FIG. 12 shows a case where the rolling roller 23 is drawn to the outer frame 25. That is, a case where the rolling roller 23 is formed of magnetized material and the outer frame 25 is formed of a magnetic material, and conversely, a case where the outer frame 25 is formed of magnetized material and the rolling roller 23 is formed of magnetic material This is a case formed by the body. With such a structure, the rolling roller 23 is drawn to the inner peripheral surface of the outer frame 25 at the large-diameter portion D1 of the wedge-shaped accommodation portion 25a, and as a result, a stable holding state is maintained in the wedge-shaped accommodation portion 25a. Becomes possible.

FIG. 13 shows that the rolling roller 23 is
The structure shown in FIG. That is,
The rolling roller 23 is formed of magnetized material,
Are made of a magnetic material, and conversely, the sleeve 22 is made of a magnetized material, and the rolling roller 23 is made of a magnetic material. By adopting such a structure, the rolling roller 23 is provided with the large-diameter portion D1 of the wedge-shaped accommodation portion 25a.
As a result, it is drawn to the outer peripheral surface of the sleeve 22, and as a result, a stable holding state can be maintained in the wedge-shaped accommodation portion 25a.

As described above, the outer frame 25 or the sleeve 2
2, or by imparting magnetism to the rolling roller 23, particularly by holding the rolling roller 23 in the wedge-shaped accommodating portion 25a so as not to be scattered, that is, not to move irregularly when the clutch is OFF. Generation of sound can be completely suppressed. In this case, the rolling rollers 23
There is no need to interpose grease or supply oil or the like around the periphery, and so-called maintenance-free can be realized.

Although the present invention has been described above, the present invention is not limited only to the embodiment, and it goes without saying that various other modifications can be made without departing from the essence of the present invention. For example, both the outer frame body and the rolling roller may be magnetized, or both the sleeve and the rolling roller may be magnetized. In either case, the rolling roller is prevented from scattering and the wedge-shaped housing portion is enlarged. A stable holding state can be maintained at the diameter.
